[USN-2185-1] Firefox vulnerabilities

[Benjamin Kaduk]

Hi Chris,

I can't seem to find any substantial amount of complaining (or really, any 
traffic at all) about this on the forums, bug tracker, or mailing lists, 
which is very confusing to me, but this firefox update appears to have 
broken printing PDFs from the in-browser pdf.js viewer.  Most of our 
systems here are running the 12.04 LTS (precise), but I think I could 
reproduce the failure on 14.04 (trusty) as well.  Even a simple "print to 
file" is sufficient to display the failure; the output is entirely blank. 
(We see a lot of blank pages in the output trays of the printers in our 
computer labs.)

I filed https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1315020 for 
tracking in Ubuntu, but the real action appears to be on the mozilla bug, 
https://bugzilla.mozilla.org/show_bug.cgi?id=1003707 .

Has anyone seen reports like this?

I tried to locally build a patched firefox with the change for mozilla bug 
991767 backed out, but the build fails, so I don't have any experimental 
data to add about whether that will help.

The build fails at:
/home/builder/firefox-29.0+build1/obj-x86_64-linux-gnu/dist/bin/xpcshell
